Oxy-Cope, and Siloxy-Cope rearrangement of cis-1-vinylcyclooct-3-en-1-ol

Creator:: Chin, Alice Wai-lee
Abstract:: Both oxy-Cope and siloxy-Cope rearrangements involve (1, 3) and (3, 3) sigrnatropic shifts. Both the concerted mechanism, and the stepwise mechanism via a diradical intermediate are possible. In a cyclic system such as cis-l-vinylcyclooct-3-en-l-ol, the thermal rearrangement takes place preferably through a diradical intermediate. At high temperature, the reaction also...

Oxymercuration of cyclodeca-1,2,5,8-tetraene

Creator:: Hong, Pak-Kong
Abstract:: The reactions of cyclodeca-1, 2, 5, 8-tetraene with mercuric salts in solvents of varying nucleophilicity are described. Instead of forming the usual oxymercuration products reported for reactions of olefins and allenes with mercuric salts, the major products obtained in the present cases result from the initial electrophilic addition of the...

The analytical application of the galvanic dissolution of niobium and tantalum : the determination of nitrogen

Creator:: VanSanten, Richard Theodore
Abstract:: Nitrogen is a contaminant of niobium and tantalum adversely affecting the workability of the metal. With recent interest in the refractory metals, one problem the chemical analyst must solve is the accurate determination of nitrogen in niobium and tantalum at very low levels. The usual method of assaying for nitrogen...

Dihalocarbene reactions with steroid olefins

Creator:: Cornelia, Richard Hartman
Abstract:: Dihalocarbenes have been generated mainly by thermal decomposition of sodium trihaloacetate and phenyl (trihalomethyl)mercury, and give gem-dihalocyclopropyl adducts with various steroid olefins. A new procedure involving the use of sealed tubes makes possible the addition of dihalocarbenes to sterically hindered olefins. In this manner, 7-cholestenyl benzoate when treated with PhHgCC1₃...

Determination of magnesium in zirconium based on ion exchange separation and titration with versene

Creator:: Metzler, Richard Kenneth
Abstract:: The Kroll Process for the production of zirconium utilizes the reduction of zirconium tetrachloride with metallic magnesium. Control of the magnesium content of the final zirconium metal is essential, as residual magnesium adversely influences the properties of zirconium. In this thesis a volumetric method has been presented for the determination...
